Real-life Escape Game - Mask and Underwear Punishment

One day, Akaha recieves an invitation for an "escape game." He thought that it would be just another puzzle game, and it was free, so he decided to give it a try. However, it seems that a strange masked man is behind the game...Akaha is locked into a room, and is unable to solve the puzzles. As soon as the game over buzzer rings, muscle men wearing only masks and a pair of underwear appear and the sexy punishment begins. Will anyone be able to beat this lust-filled game?!
